Specification of Letters Patent.

' I Application filed May 17, 1911. Serial No. 627,668.

I 'l'o'all whom 'it may concern:

Be it .knownthat LGEORGE MnIJHAR'r,

a citizen of the United States,and-a resI- dent of Whittier, in the county {of Los Angeles and State of California, have invented a new and Improved Burner, of which the following is a full, clear,

- combustion of the liquid fuel and to produce an intense flame and heat without danger of the parts becoming clogged up.

For the purpose mentioned, use is made of a fan wheel mounted to rotate in a burner bowl and having a hollow hubcarrys ing ,'a power-driven wheel for rotating the fan wheel, and feeding means arranged in connected with a liquid fuel supply to feed the liquid fuel ontothe I top of the fan wheel. 7 A pract'cal embodiment of the invention' is-represented' in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate correspondingparts in all the views.

igure 1 is a side elevation of the burner;

v jFi 2 is a plan view of the same; Fig. 3 1s bottom of the bowl E so that atmospheric.

a c ross section of'the same'on the line 33 of Fig. 2; Fig. 4 is a sectional plan view of the same on the line 44 of Fig. 3; Fig. 5 is an enlarged sectional side elevation of the feeding device; and Fig. 6 is a sectional plan view of the same on the line 6-6 ofv Fig. 5.

A suitably constructed casing A is provided in its bottom with a recess B connected by a. pipe G with a liquid fuel supply arrange to feed the liquid fuel, such as crude oil an the like, by gravity into the recess B In the upper portion of the casing A is arranged a water chamber. D closed by a cover E provided with upwardly and outwardly extending arms E supporting a burner bowl E containing a dish or .a pan F having a central openingF in register.

with a corresponding opening E in the and F into the dish or pan F, which latter is 1 provided at the opening F with a ridge F and with a water inlet K d the fan wheel G through pan F." The dish or pan F is mounted to for retaining the liquid fuel in the dish or i receive a fan wheel G secured on a hub H I extending'through the openings F? and E? and through the top of the cover E'into the be driven by water pressure in the water chamber D to rotate the fan wheel G. The

mounted 'to rotate on a tubular-bearing J water chamber D, the lower end of thesaid hub H carrying a water wheel I adapted to hub AH carrying the wheels" G and I is screwed at its lower end intothe bottom of the chamber D and opening at its lower endinto theirecess B so that the liquid fuel can pass into the tubular bearing J. A nozzle under pressure against the wheel J, to rotate the same, and the nozzle K'is connected connected with a water pressure and having regulating. the amount of water passing through the nozzle into the chamber D and against the water wheel I .so as-t'o rotate the same,-t-he bottom of the water chamber D being provided with an outlet pipe N for conducting the spent water to a suit-able place of discharge.

Within the bearing J is arran ed a feed screw 0, screwed or otherwise secured at its upper end 0 to the upper end ofthe hub H a distance above the top of the fan wheel G, as plainly indicated in Figs. 3 and 5, and the said feed screw O is provided near its upper end 0 with a groove 0 in register with ports H formed in the hub H directly above the blades of the fan wheel G K in the water chamber 'D directs water i a valve L for so that the oil carried up by the feed screw v O can pass from the groove O by way of the ports H onto the top of the fan wheel G, to be thrown o1 twardly bv the said fan wheel and thus atomizing the oil, at 'the' same time mixing it with the air drawn by the registering opening F into the dis'h or pan F. v

' The bore of the bearing J and the feed screw 0 are preferably made tapering, as plainly shown in Fig. 5, and the lower end of the feed screw 0 rests on thepointed end 1 of a screw P-screwing-in the bottom. ofthe casing A and locked thereon by a jam nut P after the adjusting screw P is adjusted, to hold the .feed screw 0 tionin thebearing J, for feeding more or fan wheel G.

It is understood that when the burner is less oil from the recess B to the top of the in use the water pressure passing into the Vicwater .chamberD acts on the water wheel I to rotate the same, and in doing so the water wheel I turns the hub -H and conseguentlythe fanJwheel-. G and. with it'the eed screw 0 so that oiE-is fed from the recess-B by the feed screw 0 upwardly within the bearing J, the oil being finally discharged onto the fan wheel G, as previously explained. I

1 It is understood that the fanwheel G has the double function 'of throwing the liquid fuel'outwa'rdly within the dish or pan F and at the same time drawing the air through the opening F so that the air is thoroughly mixed with the minutely divided liquid fuel to form a highly combustible mixture to be. burned within the bowl E It is also understood that the burning fuel causes a heating of the casing A and the parts carried thereby whereby theoil is, atomized as it ascends in the bearingJ by the action of the feedscrew O, and by making the latter and the bore of the bearing J tapering it 'is evident that .the vaporized oil can readily ascend owingto the gradual increase in the diameter of the feed screw.

It is further understood that by adjusting the screw P more or less oil can be fed by the feed screw 0 to the fan wheel G according to the consumption of the oil in the burner bowl E and as the feeding of the oil is continuous and uniform, it is evident that a proper burning and complete combustion of the fuel is had.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. burner, comprising a casing having a burner bowl provided with an air inlet, a driven fan wheel extending.in the said bowl and having a hub, a fixed tubular bearing having a lower oil inlet and extending upwardly within said hub to support the same; and a feed screw secured at its upper end to the said fan wheel and extending downwardly in the said bearing, the upper end of the feed screw delivering the oil to the said fan wheel.

2. A burner, comprising a casing having a: burner bowl provided with an air inlet, a driven fan wheel extendin in the said bowl and having a hub, a fixed tubular bearing having an oil inlet and .on which the said hub is mounted'to turn, and a feed screw securedvto the said the oil from fan wheel and extending feed screwhavinga groove for receiving the screw thread, the saidfan wheel hub having openings in register, with the said groove for the oil to pass onto the fan wheelcentrally at 'the'top.

3. A burner,,comprising a casing having a burner bowl provided with an air inlet, a driven fan wheel extending in the said bowl and having a hub, a fixed tubular bearing havingan oil inlet and on which the said 1n the said bearing, the upper end of the hub is mounted to turn, and a feed screw I secured to the said fan Wheel and extending in the said bearing,

the upper end of the feed screw delivering the oil to the said fan wheel, the said feed screw andthe bore of the bearing being conical.

4. A burner, comprising a casing having a burner bowl provided with an air inlet,

a driven fan wheel extending in the said,

bowl and having a hub, a fixed tubular bearing having an oil inlet and on which the said hub is mounted to turn, a feed screw secured to the said fan wheel and ex-f tending in the said bearing, the upper end of the feed screw delivering the oil to the said fan wheel, and a regulating screw on the said casing and engaging the lower end of the said feed screw to adjust the latter in the bearing.

5. A burner, comprising a casing having an inlet and having a water chamber closed by a cover, a burner bowl above the cover, a dish seated in the said bowl and having a central opening and-a raised rim around the wall of the opening, a fan wheel in the said dish, the said fan 'wheel having a hub provided at its upper end with openings leading to the top of the wheel blades, a fixed tubular bearing on which rotates the said hub having an oil inlet at its lower end, a feed screwjin the said bearing and secured at its upper end to the said fan wheel hub, the said feed screw having a groove in register with the said hub openings, and a water wheel in the said water chamber and attached to the said fanwheel hub.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
